Abstract 

Inulinase from Aspergillus ficuum was immobilized by cross-linking with glutaraldehyde on chitin. Batch and continuous production of fructose from Jerusalem artichoke tuber was studied using this immobililized inulinase. In a batch reactor, the extent of hydrolysis attained 90% (D-fructose/D-glucose :86/14) in 10h and 77.5g/L of D-fructose was produced from the Jerusalem artichoke tuber juice. In a continuous packed bed column reactor, the maximum volumetric productivity of 61 g/L, h was obtained at residence time of 0.9h and conversion yield of 55%. At a fixed residence time of 2.6 h and 40° C, this could be operated for over two weeks with only a slight loss of activity (4.8%).
